Costume trivia
Years after he directed "Meet Me in St. Louis", Vincent Minnelli directed "Gigi", both taking place in the early 1900s.
The dress worn by Mary Astor when she went to the fair in "Meet Me in St Loius" was sold at the MGM auction in the early 1970s. I saw it close up and it was magnificent, white on white fully embroidered or crocheted grapes, top to bottom. There was a huge hat and parasol to match. It was incredibly made, must have weighed a ton and must have cost a fortune to make.
I think that dress appears on a background woman in "Gigi" when they go to Deauville. I think it's likely Minnelli would have remembered the gown, pulled it from the costume dept and used it again, not on a featured player but in the background.
